Abstract: 553,479. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 2, 1942, No. 12366. Convention date, Sept 4, 1941. [Class 38 (v)] In order to prevent the arc being blown too quickly through an arc chute, for example in a switch such as disclosed in Specification 541,612, the exhaust end of the chute has means for restricting the venting area in response to a predetermined increase of gas-pressure. in the chute. A pair of slotted plates 14, 15 are normally pressed apart by springs 16, the plate 14 having transverse slots 14<SP>1</SP> and plates 15 having vertical slots 15<SP>1</SP>. When a certain gas-pressure is set up in the chute, the plate 14 is pressed back towards 15 and the venting area thus diminished, whereby the arc is retarded in its movement through the chute. The part 15" of plate 15 is left solid in order to retard the centre of the arc. In modifications, Figs. 3-6 (not shown), the plates have semi-registering holes, the degree of registry being, if desired, greater at the ends than at the middle so as to retard the arc-centre.

Abstract: 1417519 Automatic exchange systems WESTERN ELECTRIC CO Inc 14 March 1973 [20 March 1972] 12388/73 Heading H4K In a communication system comprising a plurality of lines arranged in hunting groups a translator 107, when forwarding to a marker 106 a translation of a first directory number into the corresponding line equipment number, simultaneously forwards an indication of the line equipment number of a second line in the same hunting group as the first to enable a connection to be made to the second line if the first is busy. In a described embodiment, Figs. 2-6 (not shown), each line link frame 100 comprises a cross-bar switching network and the line equipment numbers of two lines L1, L2 in the same hunting group differ only in their horizontal group designation. Hence, prior to making a connection to the second line having found the first busy and disconnecting therefrom, the marker retains control over the common line link frame 100. In the translator 107 (Figs. 4 and 6) the number dialled by S4 is decoded by relay trees and applied via wires (402-406) to respective translator fields (600-602) which comprise resistor matrices. One field (600) produces markings for the line link frame, which is common to both lines in the hunting group. The second field (601) produces a marking for the vertical group, which is common to the two called lines, and a horizontal group marking corresponding to the called line. The final field (602) produces a vertical frame marking, common to the two lines, and a ringing sequence marking on one of two lines, according as to whether the horizontal group designation has to be increased or decreased to find the second line, should the line first called be busy.

In a cassette arrangement (Figs. 1, 2, not shown) wherein opposite ends of a tape (15) are joined to supply/take up reels (17/16), a spring loaded control button 28 (Fig. 10C) may be latched in an operative position 28<SP>1</SP> (Figs. 10A, 10B) by engaging aprotrusion 45 with an aperture 43 in a lever 37, a motor (61, Fig. 4, not shown) being thereby energized to drive the tape transport system and also to rotate a cam 147. Alever 144 is thereupon caused to oscillate, and a pawl 142 and spring 131 force a slide 126 to reciprocate over the distance d 2  between the Fig. 10A/10B positions; simultaneously, a plate 160 (Fig. 9) which is frictionally engaged with a tape reel mount is pivoted slightly from its central rest position illustrated, and a pin on the slide 126 is able to reciprocate between positions 165A/165C in a Y-slot 166 in plate 160. When however the tape supply runs out and the reels halt, plate 160 returns to the rest position and a stop 166D restricts the movement of the pin and the slide 126; the pawl 142 which is unaffected thereupon engages a tooth 141 on slide 126 rather than a tooth 140, and then causes slide 126 to move a distance d 1  (Fig. 10C). A rod 133 then releases the button 28 from engagement with the lever 37, as shown, and the tape drive motor is switched off. The tape transport system is described with reference to Fig. 4 (not shown), a head and pressure roller raising/lowering system with reference to Fig. 3 (not shown), and further push-button latching/unlatching arrangements with reference to Figs. 5, 6 (not shown).

Abstract: 1,110,505. Automatic circuit - breakers. OTTERMILL SWITCHGEAR Ltd. 21 Feb., 1967 [22 March, 1966], No.12591/66. Heading H1N. In a circuit-breaker operating mechanism having a portion, e.g. a toggle 16, 19 which collapses to allow the contacts 1, 4 of the circuit-breaker to open, contact rebound from the open position is prevented by a latch 38 which is biased so as to engage a part, e.g. a pin 17, of the mechanism when the contacts are fully open, the latch being disengaged by the portion or toggle during an initial stage of the contact reclosing operation. In the arrangement shown, the upward movement of a pushrod 24 by a push-button or solenoid causes a latch 27 to disengage from a roller 29 to release linkage 30, 32, 35, 37. This permits the toggle 16, 19 to collapse, the contacts to open and the pin 17 to move into a recess 46 in the latch 38 where it is latched. To reclose the circuit-breaker, a yoke 21 is initially turned in an anti-clockwise direction to straighten the toggle 16, 19 and reset the linkage 30, 32, 35, 37. During this movement the pin 18 of the toggle rides along an edge 45 of the latch 38 and moves this latch so that the pin 17 no longer engages in the recess 46. Subsequently the yoke 21 is turned clockwise to reclose the contacts. The yoke 21 may be operated by a handle, a solenoid or a spring charged by a motor or by hand. Reference is made to the use of a cam and roller instead of a toggle.

Title: Improvements in Wireless Telegraphy and Telephony.
IPC: H04J9/00
Filed: 1917-09-12
Abstract: 111,649. Western Electric Co., (Western Electric Co.). Sept. 12, 1917. Addition to 102,503. Wireless signalling.-Relates to wireless signalling systems of the kind described in the parent Specification, in which a wave of radio frequency Q is modulated by a signal wave of audible frequency P so as to produce a resultant wave which may be regarded as composed of three waves of frequencies Q, Q + P, and Q - P, radiation of frequency Q being prevented and signalling being effected by waves of frequencies Q + P or Q - P, or both; the effect of the wave of frequency Q is introduced at the receiving station by a local generator of that frequency. According to the present invention telephony is effected as in the prior invention by waves of frequencies Q+P or Q-P, (where P is the mean speech frequency) and telegraphy is simultaneously effected by restoring the wave of frequency Q at the transmitting-station, In the transmitting arrangement shown in Fig. 1, a generator 1 of radio frequency and a microphone 2 are coupled by means of transformers 3, 4 to a thermionic modulator 5, the output circuit of which is coupled to a system of tuned circuits 7, 8. The branch 7 is tuned to the frequency of the generator 1 and serves as a short circuit to currents of that frequency. The parallel circuits 8 are tuned to offer a large impedance to currents of the generator frequency Q and a low impedance to currents of frequencies differing therefrom by the frequencies occurring in speech, Q Œ 1'. The circuits 8 are coupled by transformer 9 to amplifiers 10, 11 and the antenna 12. Telephony is thus effected without radiation of waves of frequency Q. Telegraphy is effected by the key 13 which connects the generator 1 through transformer 14 direct to the amplifiers 10, 11. At the receiving station, the circuit 17, Fig. 2, is tuned to frequency Q so that the telegraph signals are led through a detector 18 to the telegraph receiver 19, while the parallel circuits 20 are similar to the circuits 8, Fig. 1. Current of the frequencies used for telephonic transmission are combined with energy of frequency Q from the local generator 22, and are led to the detector 21 and telephone receiver 23.

Abstract: 1,089,886. Stove doors. FELLOWS, CHAMBEKLIN Ltd. March 25, 1966 [March 27, 1965], No. 13092/65. Heading F4W.  A door (31), for closing the combustion space of a domestic heating appliance, comprises an outer rectangular frame (32) and attached to it an inner frame member (36) which is spanned by a plurality of radiation permeable rods or tubes 44, said tubes being held in contact with one another along their adjacent sides by means of elastic heat resistant material (49) acting on the two outermost tubes. Anchorage provided by members 43, disposed along the upper 37 and lower 38 limbs of the inner frame member (36), allows movement of said tubes in a direction perpendicular to the plane of the door. The bars of each tube 44 are at all times substantially in alignment with the apertures in members 43 and limbs 37 and 38, thus allowing the room to be heated by both radiation passing from the interior of the appliance and by air which is heated on passing through said tubes. Such a closure provides for controlled combustion within the appliance without loss of room heating and at the same time, on account of the mounting which allows relative movement of the tubes, ensures that these will not crack on expansion.

Abstract: 1,034,501. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. March 26, 1964 [April 3, 1963], No. 13141/63. Heading B3M. [Also in Division B8] Apparatus for moving beams 42, 43 along a bearing surface 44 of a rolling mill cooling bank comprises a carriage 12 slidable on a beam 16. Upstanding flanges 18 support a sector-shaped plate 26 which pivots on a shaft 22 and has two stable positions in one of which, as shown in Fig. 1, it is prevented from further rotation to the right, by an extending part 30 abutting a surface 50 on the carriage 12, and in the other of which (not shown) an extending part 28 contacts a surface 48 on the carriage. A second rotatable member, in the form of two plates 32, 34 tied together by a bridge piece 36 is also pivotally mounted on the shaft 22. Stops 38, 40 are welded to the plates 32, 34 respectively for engagement with fixed abutments 60 arranged on either side of the normal extent of the travel of the carriage. The two stable positions of the plates 32, 34 are defined by their surfaces 52, 54 respectively engaging surfaces 56, 58 on the carriage. The member 26 is urged towards its stable positions by its own weight and the second rotatable member 32, 34, 36 increases this effect. In operation, the carriage is moved to the left in Fig. 1 and the extending part 28 moves the beam 42 to the left. When the carriage is moved to the right the part 28 rides under the beam and the plate 26 pivots counter-clockwise. The carriage can then again be moved to the left to shift the beam 43. The plate 26 is designed so that after the extending part has passed the beam, the weight of the plate returns it to its original stable position. When objects are to be moved to the right in Fig. 1, as the carriage is traversed, the rotatable member 32, 34, 36 pivots about the shaft 22 and the member falls to its other stable position. During this pivotal movement the bridge-piece 36 contacts an abutment 62 on the member 26 and pushes this member until it falls to its other stable position. The device is then operable to move beams from left to right in Fig. 1. The carriage 12, instead of sliding on wearing strips 14, may be provided with wheels and ride on rails.
